Samsung plasma tv 42inch PS42E THDX Blue sparkles on dark areas


Hi yes i had the same problem and its basically because the tv needs a software upgrade. I contacted argos and they sent an engineer to sort it and he plugged something into the back of the tv to upgrade it. all in all it took 5 mins to do and not had a problem since.

Lg 42pc1d plasma tv red sparkles


I had the same problem, LG came out and it turned out to be the board that filters out the interference around the screen. I pretty sure that was it, took them 10 mins to fix by replacing a few of the boards inside the screen. Sorry I can't be more specific but its not an unfixable problem, so nothing to worry about.

Vscan voltages on LG Plasma


Are your sparkles mainly red pixels flashing randomly over the TV screen, especially over darker areas? If so your sparkles are I believe a discharge problem, and can be fixed with a firmware upgrade, which I think resets and corrects the voltage and removes the sparkles, which is caused by misfiring of the gases produced with plasma TV's. I have had my TV repaired with a firmware upgrade, which takes only 10-15 minutes and is reasonably cheap repair, and now the TV looks great, no more sparkles. Don't play around with the voltages let the pros fix it, also beware! leave this too long and it can become permanent, and need a new screen which is half the price of the a new TV.

Makes you wonder why nobody is taking on the problem, doesn't it?
Well , to the best of my knowledge, it is because nobody really can.
To understand why you have to understand what do they sparkles come from.
They are random electricity discharges coming from capacitors or other components that act like capacitors, but mostly capacitors.
When laymen hear about capacitors they usually associate the word with bulged electrolytic capacitors, which often cause problems in electronics of all kind.
Well this time it isn't about them.
It's about all other capacitors - or other components exposing similar qualities - which are installed on the board. Most of them are small filter capacitors put in parallel to the big ones or to other passive components such as diodes and resistors.
The excessive heat developed by the sustain boards damages those capacitors. It hardens the electrostatic material they are made of and small breaks in it start occurring at voltages that shouldn't otherwise be causing issues.
The trouble is, they can be everywhere. You can't just pinpoint which ones were caught at fault and causing the sparkles.
When it gets REALLY bad eventually the whole capacitor burns and either shorts or, more commonly, just breaks.
Believe it or not I've seen a board that exploded before my very eyes and , after the explosion, started working LIKE A CHARM!
Turned out a small filter capacitor had blown. It as not essential for the board's functionality and after being problematic for so long and causing image deffects it had eventually shorted completely and literally exploded.
Luckily, the short it had created was too short in time and apparently in a circuit that could take the load for a short while without getting damaged.
So after it blew everything worked just great!
it's a real story from my repair experience.
Hope this helps all consumers, DIY enthusiasts and competitors alike :-)

Many TV's with an LG plasma display (or built by LG for other manufacturers) have a manufacturing defect that has been reported widely on the Internet. LG, Akai, Samsung1.gif and Zeneth among others.

The sparkles are (usually red) visible on a black background with all inputs after the set has been used approximately one year. Soon after a pop is heard and the picture no longer shows at all.

LG and some other manufacturers using the LG displays have not acknowledged this defect and will only repair them free during the warranty.

Often techs will merely adjust voltages and or picture controls, which does not fix the problem but it just disguises it -- until the display blows -- usually after the warranty expiration.

I own a 42" Akai that is 9 months old that has recently been showing the red sparkles. My set is being replaced.

You should contact service if your set has this problem is under warranty and it should be replaced at no charge.

Good luck. :)
